For engine modelers, the urge to scale back does not stop with miniaturization; it also extends to historical accuracy.

Excerpt:

The piston of Mr. Luhrs’s itsy-bitsy engine rides in a cylinder whose bore is just 1/8-inch across. The engine’s stroke — the distance that the piston travels up and down inside the cylinder — is only 5/32 of an inch. The spark plug? You could lay seven of them across the face of a dime and still see F.D.R. peeking through.
